Efficient heat dissipation composite ceramic substrate and preparation method thereof
The invention discloses an efficient heat dissipation composite ceramic substrate and a preparation method thereof. The structure of the composite ceramic substrate is SrAl12O19 ceramic/Al2O3 ceramic/SrAl12O19 ceramic. The preparation method comprises the steps: respectively preparing an Al2O3-SrCO3 mixed powder single-layer ceramic biscuit and an Al2O3 single-layer ceramic biscuit through water-based tape casting; respectively laminating the two kinds of single-layer ceramic biscuits for 5-10 layers and 10-20 layers to form an Al2O3-SrCO3 mixed powder multilayer ceramic biscuit and an Al2O3 multilayer ceramic biscuit, then sequentially laminating the two kinds of multilayer ceramic biscuits to form a composite structure casting sheet, and placing the composite structure casting sheet at 150-300 MPa for warm isostatic pressing to obtain a composite structure ceramic biscuit; and finally, discharging glue in a muffle furnace, sintering in a vacuum furnace, annealing in the muffle furnace, and performing double-sided polishing in sequence to obtain the composite ceramic substrate. The method is simple in process, and the heat dissipation efficiency of the prepared composite ceramic substrate can be improved.
